When it comes to coal fired boilers, the rear arch plays a critical role in the combustion process. The main function of the rear arch is to keep the fuel particles in suspension and prevent them from falling into the ash hopper, which can lead to incomplete combustion and decreased efficiency.
At ZOZEN, we understand the importance of a well-designed rear arch for coal fired boilers. That's why our coal fired boilers are equipped with advanced rear arch designs that enhance the combust...
Thermic fluid heater boilers are widely used in a variety of industries because of their excellent performance and energy efficiency. They offer several benefits over traditional steam boilers, including better temperature control, easy operation, and low maintenance costs. Here are some frequently asked questions about thermic fluid heater boilers:
1, What is a thermic fluid heater boiler?
A thermic fluid heater boiler is a device that uses thermal oil or heat transfer oil to transfer heat fr...
The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
Question details (Performance) :
1. The vibrating coal grate stops running totally or intermittently.
2. The current of vibrating coal grate motor rises abnormally.
3. The safety clutch of transmission machine of grate or safety pin is broken.
Answer: cause of the problem:
Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
Combustion system: The combustion system of coal-fired thermal oil heater includes base, grate, furnace, etc. The combustion system of oil/gas heat-conducting oil boiler includes furnace, burner, ignition device, etc.
Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
Control system: complete with boiler control box.
Air-smoke system: refers to the system composed of flue gas and air generated by combustion, mainly including induced draft fans...
As we all know, the transportation cost is generally related to the weight of the boiler, so how much does a 4-ton boiler weigh? How much steel does it contain? According to the fuel, 4-ton boilers are divided into 4-ton gas-fired boilers and 4-ton coal-fired and biomass-fired boilers. The amount of steel used for small-scale coal-fired and biomass-fired boilers is generally 5-7 times of the boiler output (excluding the front and rear arches), and about 25 tons for 4-ton boilers.
The primary air fan of the boiler consists of motor, impeller, casing, air inlet box, current collector, base, regulating control system, etc.
The working process of the primary air fan: Take the medium-speed coal mill and direct-fired pulverizing system as examples, the atmosphere enters the primary air fan and is divided into two paths after being boosted by the primary air fan. One path of the atmosphere enters the primary airpipe in front of the coal mill. The other path enters the air preh...
1) The insufficient heating surface. In the process of retrofit design or improvement, increase the heating surface.
2) The particle size of the fuel is large, the screening characteristics do not meet the requirements, the material concentration in the suspension section is low, and the heat transfer coefficient is small, which makes the output unable to go up, or shows that the bed temperature is high and coal cannot be added. The solution is to improve the fuel preparation system and control...
